Synthesis and anti-ovarian cancer effects of benzimidazole-2-substituted pyridine and phenyl propenone derivatives.

Given the benzimidazole derivatives have anti-ovarian cancer effects, the authors aimed to determine whether benzimidazole-2-substituted pyridine and phenyl propenone derivatives exert anti-ovarian cancer activity. 21 derivatives were synthesized and assayed for their antiproliferative activities. Western blotting in A2780 cells was used to detect the effects of compound A-6 on apoptosis-related proteins. Invasion, migration and apoptosis were assayed in SKOV3 cells treated with A-6. The activity was also examined. A-6 could inhibit proliferation, invasion and migration and induce apoptosis in SKOV3 cells. Additionally, A-6 had potent inhibitory activity in a xenograft mouse model. A-6 shows potent efficacy in the treatment of ovarian cancer and may be a potential antitumor agent.
